My recollection is that Larry Koller had an RSSE. It was pictured on the cover of the small Handguns book(1957, I believe) he published and also pictured in other places in his articles. I have been under the impression his # was 22, but have never verified it. Other than Pete Brown getting the #22 Hawkeye and Deerstalker(Pete's number was 23), none of the other early #22 single actions have turned up, to my knowledge. I have the #22 No.1, but it appears to be a latter shipped rifle. I believe it was destined to be a 21 Club rifle for Koller, but he passed away in August, 1967. The A. A. White engraved 21 Club rifles were not done until 1968, with Keith's in 1969.
